Embodiment Construction

In the following description, numerous details are set forth to provide an understanding of some embodiments. However, it will be understood by those skilled in the art that some embodiments may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.

Various services can be provided to a mobile station by a home service domain of the mobile station. Examples of such services include an accounting / billing service; a gaming service; a push-to-talk service; an instant conferencing or messaging service; a calendaring service; a location-based service (e.g., find the nearest store or other location); a presence service (e.g., service that follows the subscriber's movements); broadcast and multicasting services (e.g., relating to Internet TV); and so forth.

Thus, when the mobile station is attached to a wireless access network of the mobile station's home service domain, such services can be provided to the mobile stat...

Abstract

A first node receives information associated with a mobile station to allow for establishment of a session for the mobile station that is attached to a first wireless access network in a first service domain. In response to the received information, the first node sends messaging to a home agent in a second service domain that is of a different type than the first service domain. The first node receives, from the home agent, an Internet Protocol (IP) address allocated to the mobile station in the second service domain, where the IP address is allocated in response to the messaging, and where services provided to the mobile station are anchored in the second service domain.

Description

BACKGROUNDVarious wireless access technologies have been proposed or implemented to enable mobile stations to perform communications with other mobile stations or with wired terminals coupled to wired networks. Examples of wireless access technologies include GSM (Global System for Mobile communications) and UMTS (Universal Mobile Telecommunications System) technologies, defined by the Third Generation Partnership Project (3GPP); and CDMA 2000 (Code Division Multiple Access 2000) technologies, defined by 3GPP2.As part of the continuing evolution of wireless access technologies to improve spectral efficiency, to improve services, to lower costs, and so forth, new standards have been proposed. One such new standard is the Long Term Evolution (LTE) standard from 3GPP, which seeks to enhance the UMTS wireless network.Dual-mode mobile stations can perform access using different types of wireless access networks, such as a legacy HRPD (High Rate Packet Data) wireless access network (as de...
